摘要
为了研究锚杆加固岩体边坡后的加固效果,通过室内相似材料模型试验,在单轴压缩情况下,研究不同加锚方式对岩体抗压强度、弹性模量,锚固岩体各向异性的影响。研究结果表明：垂直加锚试件和水平加锚试件的峰值强度得到不同程度提高;垂直加锚和水平加锚在相同的加锚密度以及相同的加载条件下,不同的锚杆布置方向表现出不同的强度及变形特征;垂直加锚时试件的弹性模量比水平加锚时的弹性模量高16%~26%,表明在进行稳定性分析时,加锚岩体宜按各向异性材料进行考虑。
In order to study the reinforcement effect of an anchor rock slope reinforcement,through laboratory model tests of similar material in the uniaxial compression case and different situations,the compressive strength,elastic modulus and anisotropy of rock mass with anchor were studied.The results show that vertical and horizontal peak intensity of rock mass with anchor are improved to different degrees.Samples of rock mass with vertical and horizontal anchors with the same anchor density and the same load conditions indicate different strength and deformation features in vertical and horizontal direction.The elastic modulus of rock mass with vertical anchors is 16% ？26% greater than that of the rock mass with horizontal anchors.
